3.4.3 Blacklist

Number Blacklist is used to block an incoming call you do not want to answer
and block outgoing call.
If the incoming call or outgoing call number is registered in the number blacklist,
the caller will hear the following: "The number you have dialed is not in service.
Please check the number and try again". The system will then disconnect the
call.
